I can't stop being bitchy 😢

This all is going to sound so selfish and bitchy but I don't know what to do about it. Ever since I got pregnant (now 26w) I've been so bitchy I have no chill switch. My stepson has been extra bad. Like hes hitting kids at daycare now and doing things like jumping off furniture and spilling things on the sofa on purpose. The little time I do get to spend with my husband he has to sit in the middle of us and will kick me in the belly till I move. He doesn't see a problem with it. Im so fucking upset about it I just want to feel loved. Tonight I exploded about it. He asked about sex when he hasn't even given me a kiss in 3 days. So he told me to just go to bed if I act like that. I don't know what to do to chill the heck out and get him to pay maybe a bit of attention to me.
